.Be it known thatI, FREDERICK H. Camini, a citizen off the'United States of Amerlca, and a resident ofv Garrison, county oi Put- 1 nam, and .State of New Ycrk,have invented certain, new and useful Improvements in Sound --Reproducing Machines and Records Therefor,.of which the following is a 'specification, reference being had to-the accomsoundv -reprodu'c' pail'ing'drawings, forming apart thereof. y. inventionfrelates to improvements 1nmachines' and records therefor, and particularly to means therein. for lautc' nr1atic'all 'stopping the. .machine upon the completion'of a sound reproducing operation.

My "nven'tion consstsjin' proyidin elec'- trical circuit clo'slng,.means.1nclu a member carried by the reproducer, which is held normall out fof .contact with theface of the 'recorv while the stylus H'of vthe rei' producer. isv traveling alongthe greater portion of thesoun'd groove .in the said record, end fin--deepening .the groove, at the inner end' ther-eo whereby 'the stylus in entering.

Because -it' is undesira le thatthe terminals 27 and es which are preferably in the rena] 1 sus of iiexible should be normally in contact with the face of the record,` and it' i hel/d out of contact with the face ofthe recvis is also undesirable that the `element 26 should project beyond thefaceof the record, I have -so mounted the brushes v27 and 28 with respect to the stylus that they will be normally i 26 when the endoffthe groove is reached. It will, `ot' course, be understood that in"-y lstead of employing the *element 26 as a 4brid' e piece to close circuit through two brus es upon thetone arm, it may'itself b e employed as a circuit terminal, such a modi-l v ication being one which would be obvious to anyone familiar Vwith electrical appliances,

and in Fig. 5 I' have shown a modification in-'which such; a` terminal23 is employed, the same'being connected by awire 24 with a metallic rsleeve which is in electrical coni nectionwiththe shaft 10,the saidshaft ybeing Vconnected'by' a wire 22 with the tripping device17-. -Awire 2 1 connects the generator 32'v with `thejt'ripping device, and a wire ,20
